Do guys think I'm ugly? Or am I nobodys type?

I haven't had a boyfriend, or had anyone interested in me in over a year. Guys will flirt with me occasionally but it never turns into anything. People are always telling me that I'm pretty but it's always girls or family. So it's hard to really believe them. How do I read all this? I I'm so pretty why have I been single for sooooooo long!?
